The 2nd generation Intel Core i7-3930K Processor (Sandy Bridge-E) is super-smart, ultra-threaded, and absolutely uncompromising, making it the ultimate desktop processor for content creators and gamers. With Intel Hyper-Threading Technology delivering unmatched 12-thread performance across six cores, 4-channel integrated memory controller, and the large cache size for super low latency and quick response times, this processor will perform when you need them to, in the applications that you need them in.

A killer combination of features including Intel Turbo Boost Technology 2.0, Intel Hyper-Threading Technology and overclocking makes the 2nd generation Intel Core i7-3930K Processor (Sandy Bridge-E) devastatingly powerful. With enhanced system tuning for processor cores, memory, and power levels, you will have the flexibility that allows you to attain extra performance for more complex multimedia applications and immersive gaming. Whether you are a novice overclocker or a seasoned veteran, these processors will have you singing their praises in no time at all.

Six Core/12 Thread Processing Provides six complete execution cores in a single processor package, delivering 12 computing threads to help operating systems and applications deliver additional performance, so users can experience better multitasking and multi-threaded performance across many types of applications and workloads.

Massive PCIe Graphics Bandwidth Provides up to 40 lanes of PCIe bandwidth for PCI Express devices, which can include graphics cards, storage controllers, and additional LAN devices. This processor has more than 2X the PCIe lanes vs. other 2nd Generation Intel Core desktop processors.

Intel Turbo Boost Technology 2.0 Dynamically increases the processor’s frequency as needed by taking advantage of thermal and power headroom when operating below specified limits. Get more performance automatically, when you need it the most.

Intel Smart Cache This large last-level cache enables dynamic and efficient allocation of shared cache to all six cores to match the needs of various applications for ultra-efficient data storage and manipulation.

Intel Advanced Vector Extensions (Intel AVX) Intel AVX is a new 256 bit instruction set extension to SSE and is designed for applications that are Floating Point (FP) intensive. Intel AVX improves performance due to wider vectors, new extensible syntax, and rich functionality. This results in better management of data and general purpose applications like image, audio/video processing, scientific simulations, financial analytics and 3D modeling and analysis.

Cons: - Not cheap (a $800-1k investment with a proper motherboard)- No longer the latest and greatest (not a con for me -- after 1 year with it, I totally see this rig lasting me another 3-5 years)- Requires good cooling for overclocking

Other Thoughts: I've moved to X79 because I went beyond 2 GPUs in SLI and wanted more PCIe lanes than 2700K could provide. While the initial investment was steep ($1k with ASUS RIVE motherboard), I am very happy to have made this move! My rig had 3 x GTX 680s and now 3 x Titans in SLI driving 7.2Mpixel surround gaming, and with 40 PCIe 3.0 lanes between them those GPUs aren't bandwidth constrained at all! The latest multi-threaded aware games like Crysis 3 have not problem running on this CPU, while pushing 3 OC Titans on 95-99% utilization. (Titans are overclocked to 1,110 Mhz on GPU and 3,600/7,200 Mhz on VRAM).

This CPU is a reasonable over-clocker, with the right cooling. I have it at 4.6 GHz rock stable at 1.385v (after 12 hours on Prime95 torture test). Heard some lucky ones can get their 3930k 4.8 while under 1.4v; my sample won't be stable higher than 4.6 without going above 1.4v which I don't want. But even "only" 4.6 seem plenty for 3 overclocked Titans (with Nvidia PCIe 3.0 fix for x79), so I don't sweat.

The highest temp I observed at 4.6/1.385 was 87C with Noctua NH-D14 (with its stock 120mm and 140mm fans), and 69C with custom water loop (with Raystorm block). The max power consumer (on the package) was 189W.

It's not easy to see all 12 cores in action (since most software is not that advanced yet), but when it does happen -- WOW. The speed of encoding a video with Windows Movie Maker is surreal: a little over 1 minute for 1 hour of DVD-like quality (480p).

Buy this CPU with X79 MB until it's EOL -- it will serve you well for years!

Rating: 5/5best cpu for money

Pros: I can clock this at 4.6 and stable with corsair water cooling. I knock it down to 4.3 for general use. I have 2 7970's in crossfire. ripjaws 2400 memory. Asus p9x79 mb. Samsung 840 evo. really sweet system. amazing that windows 7 gives it only 7.8 and that's my bottleneck lol.

Rating: 5/5

Pros: Love it. Overclocks to 4 GHz easily, can go higher with even mild tuning. I get around 147 gflops at 4 GHz. Encoding, virtualization, and gaming are a breeze on this chip.

Cons: Average computers will seem slower than ever

Other Thoughts: Socket 2011 is overkill for pure gaming, but it can't be beat if you need a large amount of CPU power for multimedia editing, HD encoding, and the like. The additional PCI-e lanes also come in handy if you're going for triple or quad SLI. AMD can't even come close to the socket 2011 platform. As with most Intel processors, 1.65v RAM is not a great idea.
